The guys he played with may be able to help too. Ask them what types of discs he was throwing and how he was throwing them. They should be able to suggest 7 or 8 discs. I would suggest 2 putters, 3 mid ranges and 3 drivers with the mid range and drivers slightly varied in stability. You don't want anything too overstable. A shop should be able to help you with this info. With a decent $30/40 bag i would say he is off to a great start.
My quick 8 bag suggestion.

Get an Aviar, a Buzzz, a Leopard, and a Teebird. These four discs are classics, and plenty to get started with. If you want to get a few more discs, choose any combination of Wizard, Pure, Comet, Mako3, Roc, Heat, FD, Eagle, Volt, and Firebird. These are all widely-respected discs that the average serious disc golfer will at least be interested in trying, if not throwing regularly.

Fill out the rest of your budget with a gift card from a disc retailer, either a brick-and-mortar if there's one nearby or an online store (Disc Golf Center, Gotta Go Gotta Throw, Infinite Discs, there are others). Put enough on the card for him to pick out a bag; a basic one will be about $15–$20, and a slightly bigger/better one will be about $30–$40. He can get more discs with whatever's left over.

Volt and Firebird? Well respected, yes, but unless hubby comes with a proficient pitching background and throws FH I don't think those would be good discs for a beginner.

Swap the Aviar for a Wizard (pretty much the same thing, I know) and you've got something.

Wizard (Aviar)/Buzzz/Leopard/Teebird is about as solid a beginning setup as you could put together.

Fair point. My thinking on the Firebird was that it would be strictly a utility disc. A Volt, at least to my arm, is a Teebird substitute; not that they fly identically, but I throw them basically the same way on the same lines. If you're up to throwing one, you're up to throwing the other. But I could imagine a case being made for beginners not throwing discs with that speed and stability.
